What I found interesting was the way Pakistan's HTL(human trophic level) as progressed over the years. There is a dip between the years 1960-1980. I wonder what could have caused it. Droughts, wars, famines?
Sneaky!
Trends in the human trophic level by country
In comparison to that, Indian HTL(just for comparison, not tryna start a dick measuing contest) has more or less made a pretty steady progress.
@Roybot Now I know which uni you went to. You might wanna save the image and upload it to tinypic or something. Very few people would have PNAS access here.
